HOSE-COUPLING.

SPECIFICATION o g pa t of Letters Patent No. 763,837, dated June 28,1904.

Application filed October 2,1903. Renewed May 27', 1904. Serial No.210,082. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM H. BAILEY, a citizen of the United States,residing at Monongah, in the county of Marion, State of West Virginia,have invented certain new and useful Improvements in Hose-Couplings; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to hose-couplings; and it has for its object toprovide a device of this nature which will tightly hold two sections ofhose together and which may be quickly engaged and disengaged.

In the drawings, forming a portion of this specification, in which likenumerals of reference indicate similar parts 1 in the several views,Figure 1 is a side elevation of the complete coupler. Fig. 2 is a viewof the inner pipe-section. Fig. 3 is a view of the outer pipe-section.Fig. 4 is avertical longitudinal section through the complete device.Fig. 5 is a vertical transverse section on line 5 5 of Fig. 1. Fig. 6 isa view showing the coupling applied to a hydrant. Fig. 7 is a viewsimilar to Fig. 6, showing the invention a applied to a hose-nozzle.

Referring now to the drawings, there are provided two pipe-sections 6and 7, having collars 8 and 9 thereon, respectively, the collar 8 havinga series of projections 10 upon the forward edge thereof. The section 7is of a size to snugly receive the end of the section 6 therewithin andhas a series of notches 11, which are adapted to receive the projections10 of the collar 81 This-registration of the notches and projectionprevents the movement of the section 7 upon the section 6. The section 6has forwardly of the collar 8, and

consequently in that portion which lies with in the section 7, aplurality of grooves 12, which aline with a corresponding number ofslots 13 in the section 7.

Encircling the ends of members 6 and 7 and lying between thecollars 8and 9 is a cylindrical member 14, which is adapted for movement upon thesection 7, but which is limited in its movement by a finger 15, lying ina recess 16 of the collar 9. This member 14 is roughened upon its outersurface, thus forming a handhold which may be moved as described above.

} NVithin the member or handhold 14 are a plurality of pockets 17,corresponding in number to the slots and grooves 12 and 13, and areseparated from each other by the portions 18, as shown. These pocketscommunicate with the passage through the handhold and aline with theslots 13 of the section 7. The portions 18 are beveled on one of theirfaces, as shown at 19, so that each of the pockets 17 has an end atright angles to its curved side and an end at an acute angle thereto. Atopposite points upon the sides of the pockets 17 are recesses 17, whichare substantially the shape of right-angle triangles, the hypotenuses ofwhich lie at an angle of approximately forty-five degrees to theperiphery of the handhold.

Lying within the pockets 17 are catches 20, which project from thepockets into the slots 13 and grooves 12, in which position they areyieldably held by springs 21, which bear at their centers against thecatches and at their ends against the inner faces of the walls of thepockets 17. One end of each of the catches 20 is provided with a pair oflaterally-projecting lugs 20, which lie within the recesses 17, as shownin Fig. 4. The remaining end of each of the catches is beveled, as shownat 19, and lies against an end of its slot 13. It will thus be seen thatif the handhold be turned in the direction of the diagonal endsof thecatches these diagonal ends bearing against the ends of the slots 13will ride up over the ends of the slots and the catches moving upon thelugs 20' will rise clear of the grooves 12, and the section 6 may thenbe withdrawn from the handhold 14. In reconnecting the sections thesection 6 is inserted in the end of the section 7 and is pushed inwardlyuntil its end engages the beveled edge 23 of the catch 20. (Shown inFig. 4 of the drawings.) This beveled edge causes the catch to ride upover the end of the section 6, and the section may then be pushed homeuntil its grooves aline with the slots 13 and the catches 20 are forcedthereinto by the springs 21 to prevent disengagement of the severalparts.

In Fig. 6 of the drawings there is shown a hydrant or water-plug, whichhas a projecting spout 6, which is in the same form as the section 6 andover which the section 7 may be engaged in the manner described above tocouple a hose to the hydrant.

In practice modifications of the specific construction shown may be madeand any suitable materials and proportions may be used for the variousparts without departing from the spirit of the invention.

In Fig. 7 there is shown a hose-nozzle 30, having formed at the basethereof a member 6", corresponding to the member 6 in Fig. 6 and overwhich the sections 7 of the coupling may be engaged, as when connectingsections of hose.

What is claimed is- 1. A hose-coupling comprising a pipe-section havinga reduced end, a handhold revolubly disposed thereon and spaced from thereduced portion, said reduced portion having slots in the outer facethereof, said handhold having pockets in the inner face thereof inalinement with the slots, asecond section having an enlarged end and aresultant shoulder said enlarged end having slots therethrough, disposedwith the enlarged end encircling the reduced portion of the first-namedsection, and its shoulder bearing against the end thereof, and its slotsin alinement with the grooves of the reduced portion, blocks pivotedwithin the pockets and retractable thereinto, and lying normally withinalining slots and grooves to prevent separation of the two sections,means for holding the blocks yieldably in their normal positions, saidblocks being movable pivotally against the action of the holding means.

2. A pipe-coupling comprising two sections removably disposed one withinthe other, the inner section having grooves therein and the outersection having slots for alinement with the grooves, a revoluble casinginclosing both sections and having pockets therein, said pockets havingtriangular recesses at opposite points upon their inner faces, blocksdisposed within the pockets and having laterally-projecting lugsdisposed within the recesses, means for holding the blocks normallyyieldably projected from the pockets, and in engagement with the slotsand grooves of the two sections to prevent separation thereof, saidblocks being movable pivotally and slidably within the pockets againstthe action of the holding means.

In testimony whereof I affix my signature in presence of two witnesses.
